The Thermarest Ohm sleeping bags are ultralight performance bags that offer the roominess and comfort of a less technical bag. The Ohm bags are filled with 900FP Nikwax Hydrophobic Down which offers incredible warmth for weight and improved performance in damper conditions over regular down. The semi-rectangular shape cuts weight while allowing for unencumbered sleep and the open top is much more suitable for side and front sleepers than a standard hooded sleeping bag. The Ohm bags can be fully opened out thanks to the full length zip so can be used as a two person quilt, or two bags can be zipped together to create a roomy two person bag. The Ohm 20F provides packable warmth for 3 season camping with a comfort rating of 0 °C. This is an excellent bag for multi day backpacking if you want to go super light weight and still have a comfortable, unrestricted night's sleep. The down in the Ohm bag's Box Baffled construction uses mesh walls to maximize loft and minimize cold spots, while a drawcord at the collar seals in heat. The long side zip has a full length baffle to stop your body heat escaping through the zip.
